SYNOPSIS

DESCRIPTION

[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the
requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to
the ISO C standard.

These functions shall be equivalent to the strtol(), strtoll(), strtoul(), and strtoull() functions, except that the initial portion of the string shall be converted to
intmax_t and uintmax_t representation, respectively.

RETURN VALUE

These functions shall return the converted value, if any.

If no conversion could be performed, zero shall be returned.

If the correct value is outside the range of representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} shall be
returned (according to the return type and sign of the value, if any), and errno shall be set to [ERANGE].
